INFLUENCE OF THE LEWIS ACID ON THE NUCLEOPHILIC ADDITION TO β,β-DISUBSTITUTED α-ENONES.
Zervos, M.,Wartski, L.
, p. 2985 - 2988 (1986)
Lewis acids as BF3*Et2O, Ti(OiPr)4, ZnCl2 allow the Michael addition of lithiated aminonitrile 1 to β,β-disubstituted α-enones leading thus after carbonyl unmasking to the corresponding diketones.
